Take my word for it, Entenmann's Ultimate Crumb has nothing on Grandma's Crumb Cake!

This moist, buttery, cinnamon and sugar laced, American classic is an old favorite of my grandmother's and something of a staple at every big party.  As Grandma says,  "it's very impressive," and it goes a very long way.

 

Crumb Cake

For the cake:

1 Box Duncan Hines Yellow Cake Mix

For the crumbs:

3 cups flour

3 sticks margarine or butter

3 tsp. vanilla extract

3 tsp. cinnamon

1 cup white sugar.

Pre-heat oven to 350 degrees. 

Bake yellow cake mix in jellyroll pan according to directions on box. 

While cake is baking, make the crumbs.  Combine crumb ingredients and mix well. 

Place mixture over baked cake and bake crumbs another 10-15 minutes.
